In September 2013, the CPMA Board met with the Pest Management Regulatory Agency (PMRA) to fully explore whether any data or information that CPMA would have access to might aid PMRA in their re-evaluation of boric acid.

Based on that discussion and a review of PMRA’s risk assessment, it was our view that PMRA’s finding that boric acid posed unacceptable risks that would lead to the cancellation of structural uses was based on the use of unrealistic default assumptions.

Actual PMP use of the products is significantly lower than the “worst-case scenario” default assumptions used by PMRA in the absence of real world data.

As a result, CPMA, with support from the National Pest Management Association, collected and submitted comprehensive boric acid use data, collected from Canadian PMPs and is optimistic that the data generated will lead to fewer formulations, products and/or use patterns being removed from the professional pest management toolbox.
